SINGLE-SIDED POLO CELL AND MANUFACTURING METHOD THEREOF

WIPO Patent Application WO/2019/007189

A1

The present invention relates to the field of solar cell manufacturing technology, and more particularly to a single-sided POLO cell and a manufacturing method thereof. A silicon oxide plus polycrystalline silicon layer is used for backside passivation. The effects include firstly, surface defects on the back side are passivated, weak light responsiveness is enhanced, contacts between the metal and the semiconductor on the back side are also passivated, and the negative charge value of contacts is reduced; secondly, no transverse transmission of minority or majority carriers is present in a substrate region due to the complete passivation and the lack of point contacts; and thirdly, the polycrystalline silicon has an indirect bandgap so current loss is minimal.
